\huge\longmapsto\mathfrak{Answer}

=》

\sec {}^{2} (x)  - tan(x) - 3

=》

\tan {}^{2} (x)  + 1 -  \tan(x)  - 3

=》

\tan {}^{2} (x)  -  \tan(x)  - 2

=》

\tan {}^{2} (x)  -  2\tan(x)  +  \tan(x)  - 2

=》

\tan(x) ( \tan(x)  - 2) + 1( \tan(x) - 2)

=》

( \tan(x)  + 1)( \tan(x)  - 2)

so,

case - 1

=》

\tan(x)  =  - 1

case - 2

\tan(x)  = 2

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 22 inches and a height of 66 inches
icang [17]

Answer:

The height of the new cones will be 16.5 inches.

Step-by-step explanation:

We know that,

The volume of a cone is,

V=\frac{1}{3}\pi r^2 h

Where, r is the radius of the cone,

h is the height of the cone,

In the original cone,

r = 22 inches,

h = 66 inches,

Thus, the volume would be,

V_1=\frac{1}{3}\pi (22)^2(66)

Also, for the new cone,

r = 44 inches,

Let H be the height,

So, the volume of the new cone would be,

V_2=\frac{1}{3}\pi (44)^2(H)

According to the question,

V_2=V_1

\implies \frac{1}{3}\pi (44)^2(H)=\frac{1}{3}\pi (22)^2(66)

\implies H=\frac{22^2(66)}{44^2}=(\frac{22}{44})^2\times 66 = \frac{66}{4}=16.5

Hence, the height of the new cones will be 16.5 inches.

There are 27 girls and 36 boys who want to participate in a math competition. If each team must have the same ratio of girls and
Reptile [31]

Since the ratio of girls and boys must be the same in each team, and all the competitors must be involved, it means that each team's ratio of boys : girls must be equal to the total ratio of Boys : Girls = 36 :27= 4 / 3.

Now 4 / 3, the most simplified version of 36 / 27, happens by dividing the numerator & demoninator by 9 (the greatest number it can divide by). So the greatest number will be 9 teams, each of  4 Boys & 3 Girls
